Waves

Question 1

Longitudinal wave

Answer 1

A type of wave in which the disturbance moves in the same direction that the waves travel

Question 2

Crest

Answer 2

The higher point, or peak of a wave

Question 3

Trough

Answer 3

The lowest point , or valley of a wave

Question 4

Amplitude

Answer 4

The maximum distance that a disturbance causes a medium to move from its rest position the distance between a crest or trough of a wave and a line through the center of a wave

Question 5

Wave Length

Answer 5

The distance from one wave peak or crest to the next wave length can be measured as the distance from any part of one wave to the identical part of the next wave

Question 6

Medium

Answer 6

A substance through which a wave moves

Question 7

Mechanical Wave

Answer 7

A wave, such as a sound wave or seismic wave, that transfers kinetic energy through matter

Question 8

Transverse Wave

Answer 8

A type of wave in which the disturbance moves at right angles or perpendicular to the direction in which the waves travel

Question 9

Frequency

Answer 9

The number of waves that pass a fixed point in a given amount of time usually one second the number of cycles per time

Question 10

Reflection

Answer 10

The bouncing back of a wave after it strikes a barrier

Question 11

Wave

Answer 11

A disturbance that transfers energy from one place to another without requiring matter to move the entire distance

Question 12

Refraction

Answer 12

The bending of a wave as it crosses the boundary between two mediums at a angel other than 90 degrees

Question 13

Diffraction

Answer 13

The spreading out of waves as they pass through an opening or around the edges of an obstacle

Question 14

Interference

Answer 14

The meeting and combining of waves the adding or subtracting of wave amplitude that occurs of wave amplitudes that occurs a waves overlap
